Abstract

Cette invention se rapporte à un système de filtre (10) conçu pour être utilisé avec une bouteille (11) présentant un goulot ou une extrémité ouverte (12) ayant une section transversale circulaire. Ce système de filtre contient un milieu filtrant fin (17) ayant une poromètrie moyenne d'environ 1 à 3 microns et capable d'éliminer les contaminants de 3 à 4 microns et davantage, ainsi qu'un milieu filtrant intérieur (22) disposé radialement à l'intérieur du milieu filtrant fin. Le milieu filtrant intérieur renferme du charbon activé, de préférence une matrice de plastique et de charbon activé poreuse, présentant une porosité comprise entre environ 10 et 150 microns. Une enveloppe extérieure (13) contient le milieu filtrant et le milieu filtrant intérieur et elle est dimensionnée de façon à pouvoir passer à travers le goulot ou l'extrémité ouverte de la bouteille. Le milieu filtrant fin comporte de préférence des feuilles (18, 19) sur les faces opposées d'un milieu filtrant à microfibres (20) constitué par des microfibres de verre dont les diamètres de la section transversale varient, le milieu filtrant fin ayant une structure plissée ou en accordéon. On peut également prévoir un système de filtre comprenant une paille (58) maintenue pressée par ressort. Ce système de filtre peut également comporter une enveloppe en plastique généralement tubulaire (13) pourvue d'un certain nombre de nervures (15) ayant chacune une surface interne et une surface externe au moins 50 % plus grande que la surface interne. On peut également prévoir un élément filtre comprenant une matrice rigide poreuse d'au moins 35 % de charbon activé, de styrène et d'un polymère d'élimination des métaux lié au styrène. Ce système de filtre peut également comprendre une enveloppe d'élément filtre s'étendant vers le haut à partir d'un bouchon et reliée opérationnellement audit bouchon, cette enveloppe ayant une superficie de section transversale maximum au moins 20 % plus grande que la superficie du dessus du bouchon, par exemple sous la forme d'un disque ou d'une sphère. On peut former ce filtre en accouplant des parties hémisphériques, et l'enveloppe peut avoir une configuration nouvelle.
